8301 What operations can be used depends on the particular DOCUMENT and its
8302 handler application, but typically it is one of the following common
8303 operations:
8304
8305 \"open\" - open DOCUMENT, which could be a file, a directory, or an
8306 executable program. If it is an application, that
8307 application is launched in the current buffer's default
8308 directory. Otherwise, the application associated with
8309 DOCUMENT is launched in the buffer's default directory.
8310 \"print\" - print DOCUMENT, which must be a file
8311 \"explore\" - start the Windows Explorer on DOCUMENT
8312 \"edit\" - launch an editor and open DOCUMENT for editing; which
8313 editor is launched depends on the association for the
8314 specified DOCUMENT
8315 \"find\" - initiate search starting from DOCUMENT which must specify
8316 a directory
8317 nil - invoke the default OPERATION, or \"open\" if default is
8318 not defined or unavailable
8319
8320 DOCUMENT is typically the name of a document file or a URL, but can
8321 also be a program executable to run, or a directory to open in the
8322 Windows Explorer.
8323
8324 If DOCUMENT is a program executable, the optional third arg PARAMETERS
8325 can be a string containing command line parameters that will be passed
8326 to the program; otherwise, PARAMETERS should be nil or unspecified.
8327
8328 Optional fourth argument SHOW-FLAG can be used to control how the
8329 application will be displayed when it is invoked. If SHOW-FLAG is nil
8330 or unspecified, the application is displayed normally, otherwise it is
8331 an integer representing a ShowWindow flag:
